writing of the commencement thereof; but the failure to so notify the Company shall not relieve the Company from any liability hereunder, except and to the extent it is materially prejudiced as a result thereof, and in any event shall not relieve it
from any liability which it may have otherwise than on account of this Section 6.3, except to the extent that the failure to so notify the other party is a defense to such other liability. 
 (d) The Borrower shall pay, and hold the Lender harmless from and against, any and all present and future stamp, documentary, and other similar taxes
with respect to the Notes, this Agreement and any other Transaction Documents, any collateral described therein, or any payments due thereunder, and save the Lender harmless from and against any and all liabilities with respect to or resulting from
any delay or omission to pay such taxes. 
 (e) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives,
any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement, any other
Transaction Document, the transactions contemplated herein or therein, the Subordinated Term Loan or the use of proceeds thereof.

 (f) All amounts due under this Section shall be payable promptly after written demand therefor.

 Section 6.4 Successors and Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the Borrower may not assign or transfer any of its
rights or delegate any of its obligations hereunder without the prior written consent of the Lender (and any attempted assignment, delegation or transfer by the Borrower without such consent shall be null and void). 
 (b) The Lender is purchasing the Notes without any view to “distribution” of such Notes within the meaning of the Securities Act. The Lender
may at any time sell some or all the Notes, or participations or assignments in all or a portion of its rights and obligations under this Agreement, the Notes and the other Transaction Documents; provided, any such transfer shall be made in a
manner that does not require the Company to register the Notes under the Securities Act or any applicable state securities or blue sky laws. Any Holder of Notes shall be deemed to have all the same rights granted to SunTrust hereunder and under the
Notes and other Transaction Documents. 
 Section 6.5 Governing Law; Jurisdiction; Consent to Service of Process.

 (a) This Agreement and the other Transaction Documents shall be construed in accordance with and be governed by the laws (without
giving effect to the conflict of law principles thereof) of the State of New York. 
 (b) The Borrower hereby irrevocably and unconditionally
submits, for itself and its property, to the non-exclusive jurisdiction of any Federal and/or state court located in the State of Georgia and any appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any other Transaction Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in any such court. Each of the parties hereto agrees that a final nonappealable judgment in any such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by applicable Law. Nothing in this Agreement or any other Transaction Document shall affect any right that the Lender may otherwise have to bring any action or proceeding relating
to this Agreement, then Notes or any other Transaction Document against the Borrower or its properties in the courts of any jurisdiction. 
 (c) The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding described in paragraph (b) of this Section and brought in any
court referred to in paragraph (b) of this Section. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

 (d) Each party to this Agreement irrevocably consents to the service of process in the manner provided
for notices in Section 6.1. Nothing in this Agreement or in any other Transaction Document will affect the right of any party hereto to serve process in any other manner permitted by law. 
 Section 6.6 WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT
IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT, THE NOTES OR ANY OTHER TRANSACTION DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER
THEORY). 
 Section 6.7 Counterparts; Integration. This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Notes the other Transaction Documents, and any
separate letter agreement(s) relating to any fees payable to the Lender or any of its Affiliates constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements
and understandings, oral or written, regarding such subject matters. 
 Section 6.8 Survival. All covenants, agreements,
representations and warranties made by the Borrower and the Borrower Parent herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other
parties hereto and shall survive the execution and delivery of this Agreement and the purchase of the Notes, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Lender may have had notice or
knowledge of any incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on the Notes or any other amount payable or
obligation under this Agreement or the Notes is outstanding and unpaid. The provisions of Section 6.3 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment
of all of Borrower’s obligations, or the termination of this Agreement or any provision hereof. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement or
the Notes shall survive the execution and delivery of this Agreement, the Notes and the other Transaction Documents, and the issuance and sale of the Notes. 
 Section 6.9 Severability. Any provision of this Agreement or any other Transaction Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be
ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular
provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information
includes the name and address of the Borrower and other information that will allow the Lender to identify the Borrower in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent
commercially reasonable, such information and take such other actions as are reasonably requested by the Lender in order to assist the Lender in maintaining compliance with the Patriot Act.
